Run import pyBluzelle
Run my_connection = pyBluzelle.create_connection(localhostIP, port, UUID)
Ready for test
Try it in the python interpreter

>>> import pyBluzelle
>>> b = pyBluzelle.create_connection("127.0.0.1", 51011, "137a8403-52ec-43b7-8083-91391d4c5e67")
>>> b.create("kk","1234")
True
>>> b.read("kk")
'1234'
